It's great for stubborn bolts here in NY from our salty winters.

You clearly have no clue how to wrench.

You are wrong on that. Have tried multiple penetrating lubricants and it just works the best.

This stuff works well, if it's a really rusted and seized bolt, you'll need to spray and let it sit a while, then spray again. Maybe use something to knock some of the rust off to help it penetrate to the threads.

Used it the other day on an old hitch lock that would not function. A few quick sprays with this and it's working as new and I was able to avoid a $75 locksmith call.

Yea the wd40 does smell less bad, but no idea which is worse because both failed when I used it, had to cut off the nut.

So have I, and none of them have ever done what they say on the tin. They're thinned oil, that's it. They don't penetrate anywhere regular old WD-40 doesn't already.

I've gone through the "you're not using it right" steps given by everybody who swears by them a dozen ways and never found different. Hell, project farm's testing even had WD-40 straight up beating pb plaster, though the results were basically indistinguishable from using nothing at all.

The only thing that works reliably is heat. Sometimes a lot of it. If something just needs a little oil to get moving right then use whatever is laying around - it'll all work the same. PB Blaster is snake oil.

Or hell, it'd be better if it were snake oil. Might smell better.

It puts out so many VOCs, you can't even buy it in California anymore.

Kroil is way better than most other stuff I've tried including this. I've put it on stuff so rusted that even 1100ft lb torque wrenches couldn't the bolts off. Sprayed it on left it overnight and the bolt came off with a wrench by hand. It's saved me multiple times. I've used it to remove bolts on headers that are notorious for snapping off.

I completely agree. PB blaster really doesn't work for most things I have tried it on. Kroil kills it.
